"I've already put it away, Dean Lin En!"
On the high ladder placed in the open space, Lydia waved her hands and shouted loudly. The reason why the light bulb was placed so high was naturally so that everyone could see it!
"Then let's start!" Linn nodded, looked at Alok and others beside him, and asked them to start the motor.
The sound of "thump thump thump" immediately resounded throughout the castle, startling the poor people who were watching from a distance.
This motor also uses the principle of cutting magnetic flux lines, and is not protected by a shell. Everyone can see the tiny arcs flashing around the motor's rotor when it is moving rapidly.
A steady stream of current is being transmitted to the light bulb through the wire.
Dozens of fire lion hairs intertwined inside and twisted into a spiral glowed faintly.
After a while, the light became brighter and brighter, and soon overshadowed the dim light brought by the surrounding torches, illuminating the entire open space as if it were daytime.
Reidel and others, who were looking directly at the light source, could not help but squint their eyes under such a powerful and dazzling light, or subconsciously covered their bodies with their hands. It felt like they were watching the noon. The sun is normal.
"Lightning, they trapped lightning in that ball!" Someone in the crowd shouted with a trembling voice.
Ham and others also stared in astonishment at the light bulb that was continuously emitting light in the air, and then looked at the motor that was constantly rotating.
They had previously thought about what methods the wizards would use to make the night the same as the day, but they did not expect that their method would be to bind the lightning!
The light emitted by the light bulb spread far away. The poor people hiding in the house couldn't help but look through the windows to the open space where the crowd gathered. It was like a small sun rising here...
Lin En was extremely satisfied when he saw this scene. They had verified it in the laboratory before, but this should be regarded as the first experiment conducted outdoors.
This is their first step into the electrical age!
The performance of the fire lion's hair is much better than Lin En expected. The only drawback is the short life expectancy. According to his estimation, even the hair cut off the fire lion's body will be burned by the high temperature within half a year. .
Of course, in a sense, that is not a disadvantage...
And compared to tungsten wire, this biological material is extremely environmentally friendly and can be infinitely regenerated...
"It seems that there will be no more dark nights in Ietta in the future." Philip said with emotion. The material for making this kind of light bulb is not complicated. There are also a lot of magnetic minerals in the Kingdom of [Hadra Tower]. He can foresee that in the near future In the future, lights will illuminate every corner of the city.
"It's like a little sun!" Reidel murmured.
"It's not even close. A real artificial sun is tens of thousands of times more dazzling than this!" Lin En said with a smile.
Hearing this, everyone present looked at Lin En with strange expressions, saying this as if they could really create a sun.
"So light is electricity and electricity is light, right? Professor Linn?" Jonny pondered for a long time and suddenly asked.
They introduced electricity into the fire lion's hair to create light. Is that how the light they feel on daily basis comes from?
This question actually stopped all the official wizards like Philip for a while, and everyone frowned in thought.
"Isn't that right? The forms of light and electricity are different, and we can also create light in other ways." Orlando shook his head and raised his hand to condense a fireball. "For example, can we say that fire is light?"
In the land of wizards, there has always been talk of the element of light, and many wizards want to understand the secret.
It's just that the 'light element' is very difficult to deal with. It seems to be everywhere and elusive, and it cannot be sensed with magic at all.
However, they still concluded a lot of rules. For example, light is often born with heat and can be reflected, absorbed, etc., and developed a lot of magic that uses light.
"Your idea is good, Jonny, but you have to explore this secret yourself!" Linn couldn't help but laugh, and did not mean to directly tell the answer. After all, the exploration of the laws of the world must be done step by step. Only by going through all the wrong and right ones can we have a truly complete magic theory.
"Which of you can study light thoroughly? No, even just a little bit of it is enough to get a Corona Medal and leave a mark in the history of magic!" Lin En said solemnly.
Medal of the Sun?
Hearing what Linn said, Alok and others were very excited. That was the highest award in the magical world!
Even Lydia is a little bit ready to make a move. She has no magic talent and it is estimated that it will be difficult to pass the official wizard exam, but this does not prevent her from becoming the first wizard apprentice to receive the Corona Medal!
"Professor? Then where should we start exploring the secret of light?" Lydia asked eagerly.
Orlando was amused for a moment. If the dean knew, he would have mentioned it long ago and would have left the opportunity to them.
However, to his surprise, Lin En took out a crystal clear glass from his pocket and shook it in front of everyone.
"You can start with it!"
"Dean, isn't this just an ordinary piece of glass?" Alok curled his lips.
Glass products may be very precious in the Kingdom of [Hadera Tower], but in Iyetta even ordinary civilians can afford them. Even when the school was expanded, they planned to put them on the windows in order to have better light transmission. Nothing special.
"To be precise, this is a prism!" Linn explained with a smile and placed it under the light. Only then did everyone present realize the difference.
This triangular prism looks like a fine gem. Light enters from one side of the prism and emerges from the other side after refraction. However, the refracted light is not bright white, but an extremely gorgeous line - by The gradient color layer composed of seven colors: red, orange, yellow, green, cyan, indigo, and purple, is extremely dazzling when projected in the shadow...
Alok and others looked at the scene in front of them in surprise.
The light... was actually separated!
"The white light we saw turned out to be so beautiful!" Lydia said in surprise and delight.
"Professor, what is the principle of this?" Peirce tried to stretch out his hand and swayed back and forth on the spectrum. The colorful light shone on his palm, feeling vaguely warm.
"Is this only a phenomenon of light produced by electricity? Or is it all light?" Philip on the side also asked eagerly.
